Vitamin D Deficiency Is Associated with COVID-19 Severity and Mortality

On April 7th, we proposed that Vitamin D might be important in COVID-19 infections based on the timing of the pandemic and the “at risk” populations. We cited literature showing that Vitamin D sufficiency reduced the risk of acute respiratory infections and the severity of infection by other viruses. We found several studies using high-dose Vitamin D in patients on ventilators that showed improved outcomes including decreased mortality. A month ago, we called for more research. Now, new studies in COVID-19 patients suggest Vitamin D sufficiency might reduce disease severity and death. Read more.....
